Germany hosts its national elections today, September 24, to elect the members of the 19th Bundestag. The new Bundestag will have to elect a Chancellor with an absolute majority of its members, who will in turn form a new government.
The Christian Democratic Union/Christian Social Union (CDU/CSU), led by Angela Merkel, has maintained a double-digit lead over the Social Democratic Party (SPD) in opinion polling since the 2013 election, aside from a period in early 2017 following the selection of Martin Schulz as SPD leader.
Wikipedia: Germany uses the mixed-member proportional representation system, a system of proportional representation combined with elements of first-past-the-post voting. The Bundestag has 598 nominal members, elected for a four-year term; these seats are distributed between the sixteen German states in proportion to the states’ population eligible to vote. Every elector has two votes, a first and a second vote. 299 members are elected in single-member constituencies by first-past-the-post based just on the first votes. The second votes are used to produce an overall proportional result in the states and then in the Bundestag. Seats are allocated using the Sainte-Laguë method.
The German Bundestag is the representation of the people of the Federal Republic of Germany and, being vested with decisive legislative authority, its most important body. It is composed of representatives of the German people who are elected for four years in general, direct, free, equal and secret elections.
